Priscus Attalus - Augustus (usurper) of Imperium Romanum from 409 AD to 414 AD
Priscus Attalus was twice Roman usurper (in 409 and in 414), against Emperor Honorius, with Visigothic support.

He was an important senator in Rome, and was twice proclaimed emperor by the Visigoths, in an effort to impose their terms on the ineffectual Emperor Honorius, in Ravenna.

He held the title of Emperor in Rome, during 409, and later in Burdigala in 414. His two reigns lasted only a few months. He was abandoned by the Visigoths and eventually captured by Honorius' men and finished his days in exile.

He was the last non-Christian Roman emperor.
